Hey y’all. I’m honestly lost and feel super down.

  • Facts: CBF1000 sc58
  • Last thing I did was get my alternator and regulator repaired/changed. My alternator was burnt out. The mechanic said that it’s am usual problem with this model and the regulator is the problem.
  • I had to learn to take it out and rebuild it myself. About a month ago, I finally put the alternator back in and my bike actually started! I was overjoyed.
  • Since a week now I’m trying to actually ride it again and it won’t start. I recharged the battery (Li-ion). When I tried starting it, the battery kinda drained immediately. It just didn’t start. Luckily, I have a second (gel) battery that was full. I put that in and my bike didn’t even light up. The fuses all look fine to me. The cables should be correct (there aren’t that many options).

I just don’t even know where to start. Thanks for reading

    Well. Something is definitely wrong. I think the Li-ion battery is fried, it’s losing charge immediately after unplugged from the charger. It powers the bike enough to try to start it, but then falls off to under 10V. The gel battery doesn’t even get there, it’s losing charge apparently immediately when I press the starter.

    There’s no leakage, as far as I can measure. About the grounds, I still don’t know. But it seems like that could be the issue. I don’t know if I can do that whole measuring on my own though. Maybe I need a mechanic to pick up my bike and pay for that. I just don’t have the equipment or space to take my bike apart, check the spark plugs or anything. Do you maybe have a good tutorial for dummies like me on how to check the grounds?

      Easy check is disconnect negative from battery, set the DVM to continuity (the beepy mode), check that the DVM works first (make a beep), then test the connection between batt negative, and:

      • Frame
      • engine
      • regulator negative (you can poke the sharp tip right into the copper)
      • Anything else you suspect

      That’s the critical stuff.
